I haven't read all five pages but Cosworth has developed a 400 horsepower N/A motor...It can be had for around 30K. Not trying to be sarcastic or anything. It can be done and some people work very hard to stick N/A and be the most power N/A...But it's not cheap.

I don't really have the time to go into detail about all of the costs associated with going N/A, but it is not cheap. If done right, you can piece together, fab, and install a turbo system for cheaper than a full N/A setup. Tuning knowledge is extremely important though, so turbocharging a factory N/A car is not for rookies. :tup: Then again, as long as there is a reputable tuning shop in your area, you should be golden.

The way I see it is if you're going to break your warranty, you might as well do it for more power.

Oh and as far as longevity goes, low boost is your best friend. At 5-6 psi, your car will last longer than you will own it.

Anyway, I'm done. It's all in what you want to do and there is no right or wrong. Just opinions. I just hate how some of you folks blast people about things and try to make them feel like a fool. Hell, it is almost as bad as my350z at times.

I did acknowledge that there are some well designed out of the box kits out there, go back and read. The thread asks about getting 400 without a turbo, hence your post is completely irrelevant to the thread. Your opinion might not be wrong, its just in the wrong place.

Some of us folks are just sharing experiences and adding some personal insight and experience. I did not blast anyone. Whats the point of buying a turbo kit and running low boost? To make 60hp? Whoopee!! You said "if" done right. The problem is that it is extremely hard to get 100% right the first time around. I have been around many many builds and maybe one in ten start and idle the first time the motor turns over. And these are builds done by people who compete in timeattack events all over the country and build 500whp cars all day long. The average joe is at a big disadvantage. Unless, like I already said, they go and drop off the car and a wad of cash at the local shop and come back to get it 2 weeks later.

Also honestly, unless you are going to track the car with race tires on...big power becomes completely useless on the street.

Remember, there are idiots everywhere you go in ALL horsepower classes and ALL kinds of vehicles. Quit your whining and go back to your Enfamil formula.

Chill out. Getting worked up over something like this is immature and completely pointless. Learn to respect others opinion without getting upset and start an unnecessary argument. There is always more than one way to deal with the situation, the first one you think up is the emotional one, often not the best choice... If you dont want it to turn into my350 then don't turn it into my350.

I really cant wait to start seeing what people are getting out of this engine NA... Its going to be so fun finding the right setup.

$14K gets you an LS7... So for half the loot, you can drop in a 505HP 500Lbs/Tq motor. :D Much cheaper and still extremely reliable.

If you're going to go N/A and spend that much money, might as well do a motor swap.

Agreed...However then you're talking about a new transmission and driveline that will work with the LS setup. So you'r back up to over 20 by the time everything's installed and operating. At least in my mind...I could be wrong. I think you're right about doing a motor swap though. There are conversion kits out now for the Titan motor fitting into the Z's. I'd bet you could easily achieve over 400 HP N/A and fit within a 15K budget.

LSx swap is always a good option. :)

JoeyD 02-24-2009 01:36 PM

LS7 is the only stock motor I have ever seen blow...

RCZ 02-24-2009 06:13 PM

Really? You should check out some RX-7's . Not to mention you can blow anything if you drive it stupidly enough.

You're reading into what I was saying far too much - the short point is that, from my side of the fence, I plan on modding with the purpose to race the car at a track. If you want to mod it to have some ridiculous amount of horsepower, have at it I guess. But I see that on par with getting chrome 24's on a Hummer - a vehicle that'll never do what its designed to do.

Sounds like you did a little street racing with your SRT-4 and I hit a nerve, to be perfectly honest. I never said I was innocent, myself. But after a couple eye-opening incidents, never again.


Bobo, come on. I am not focusing on 370z's, or anything like that. I just simply said that people of all walks of life in all kinds of vehicles do stupid things. I don't street race, btw. The main reason why I want to step out of my SRT-4 is because I don't want to be looked at in that manner. :( Unfortunately, people that drive SRT-4's, etc have a bad reputation because well.... most of the drivers are young and dumb. :ughdance:

I agree about your comment about the message boards. I am poor at determining if someone is being offensive at times, so I apologize about that. I am just sick of seeing people whine about things all the time and that counts for both sides of the enthusiast fence in this discussion. Then again, what is life without a little debate every now and then?????? :roflpuke2:[

G&M Performance 02-24-2009 08:45 PM

Look, I don't need advice. I appreciate your concern, but maybe this online discussion thing isn't for me because people have a tendency of misunderstanding one another. Additionally, I don't appreciate the fact that you're calling me "immature." You don't know how I operate on a daily basis, so don't fly off of the handle and label people when you see a post that is a bit on the passionate side.

Anyway, the soldier that fabricated this thread just wanted to know if NA was a feasible option and I provided him with my opinion. You thereafter posted yours, which seemed to target my opinion, and I countered it because I wanted to let you know that boosting is cheaper than going N/A. Simple enough, huh? I'm sorry if I offended you or pissed you off.

Don't forget that I also stated that a well tuned boosted car can last longer than most people own their cars. By today's standards, that means 3-5 years. There are OEM cars that are boosted that last 10+ years that require periodic maintenance with the turbocharger. Again, it is all in how the vehicle is tuned. Oh and it is also all in how it is cared for.

Finally, a car running 6psi on a large displacement motor can make plenty of power. Sometimes more than 60hp. :tup: Also, the money that it would take to get to the soldier's target hp naturally aspirated would cost more than it would to turbocharge it. You know, it's all in what he wants to do in the end, right? As long as he surrounds himself with the right people and dedicates himself to learning how to boost, build N/A, or whatever, he can minimize the chances of his car going kaput.

And by the way, are you saying that making big power is 400whp and is not good for a streetable setup? Please elaborate!


P.s. NA for the 370 will definitely be a change from the 350.

I want to thank all you guys..
 
For all the information and great feedback. Keep the info coming, this thread is going to help alot of people out, current owners as well as future ones. Actually this may prompt people to buy, with all the mods coming out.:tup:

Meh. It's a pretty much maxed out N/A motor, but makes a good twin turbo motor.

JoeyD 02-25-2009 10:16 AM

I don't know if I would consider a high compression V8 a good canidate for turbo. The one I watched go was rev'd to the limit and the valve train essentially disentegrated. Who cares if it's hand build if it just spins itself apart. That being said GM handled it well and as far as I know the car is still going strong on motor #2. Also, if I had the money I would have a hard time choosing between Godzilla and a Z06. The Z06 is just so much fun to drive.

Lingenfelter has done some pretty amazing things with turbo's on the Corvette V8's. Ford GT owner's are pumping out 1,400 horsepower with stock internals out of their 5.4 liter V8's with twin turbo kits.

ALOT of the sandrails and dune buggies I've seen run twin turbo LS or Northstar V8 motors. Twin turbo V8's are an absolute blast!!!

I think for the most part you're right about non-built V8's and twin turbo kits not being a good match but if everything is built right then they can be a lot of fun.
